Microscopic quantum generalization of classical Liénard oscillators
Srijan Bhattacharyya, Arnab Ghosh, Deb Shankar Ray
Based on a system-reservoir model and an appropriate choice of nonlinear coupling, we have explored the microscopic quantum generalization of classical Liénard systems. Making use…
Systematic designing of bi-rhythmic and tri-rhythmic models in families of Van der Pol and Rayleigh oscillators
Sandip Saha, Gautam Gangopadhyay, Deb Shankar Ray
Van der Pol and Rayleigh oscillators are two traditional paradigms of nonlinear dynamics. They can be subsumed into a general form of Liénard--Levinson--Smith(LLS) system. Based on…
Nonlinear dynamics of emergent traveling waves in a reaction-Cattaneo system
Pushpita Ghosh, Deb Shankar Ray
Standard diffusion equation is based on Brownian motion of the dispersing species without considering persistence in the movement of the individuals. This description allows for th…
Parametric oscillations in a dissipative bosonic Josephson junction
Abhik Kumar Saha, Deb Shankar Ray, Bimalendu Deb
We study the dynamics of a nonlinear dissipative bosonic Josephson junction (BJJ) with a time-dependent sinusoidal perturbation in interaction term. We demonstrate parametric reson…
